Does anyone know what the actual RICA law is with regards to hosting providers, and their clients?

i.e. does web hosting providers need to require RICA verification for every client on their servers? I don't know about you, but it's physically impossible todo this. We don't have a shop in every single town in the country and cannot verify every client whom we don't see face to face.

And what about our international clients? What do we do with them.
